Google extended YouTube Partnership Program to individual popular videos that accumulates lots of views. If your video is eligible for monetization, you’ll receive an email and see an "Enable Revenue Sharing" message. Once you've chosen to enable revenue sharing, YouTube’ll sell advertising against your video and pay you a revenue share into your Google AdSense account each month. Individual video partnerships’ll not be eligible for many of the benefits of user partnerships, like enhanced channel features or the ability to monetize other videos in your account. For now individual video partnerships’re available only in the US, but soon it’ll roll out internationally.
